Researchers hope that Prader-Willi syndrome, a genetic condition that causes unremitting hunger, could help in the development of future treatment for obesity. Experts do not yet understand the mechanism behind the syndrome except that incessant appetite stems from impaired function of the hypothalamus, the part of the brain that controls appetite. If the mechanisms behind this disease are discovered it could shed light on appetite and hopefully obesity as a whole.
